Show which muscle is working —
live

Three situations every trainer knows

“I can’t feel my glutes.”

You explain, correct, tap the muscle, and the thigh still takes over. With easyEMG your client sees their glutes as a live curve. In HOLD mode they keep activation inside a target zone and notice immediately when it drops.

“My left side feels different from my right.”

With two or four sensors, SYMMETRY compares both sides in real time. Differences become visible instead of assumed. Repeat the measurement in a later session and compare directly.

“My technique falls apart at the end of the set.”

The report shows the fatigue trend across the recording (median frequency as a curve), most meaningful in holding exercises. A visualisation for your own judgement, not an assessment by the app.

Target zone — large live values, readable from a distance

SYMMETRY — both sides in the target zone at once

Mind-muscle connection: what the research supports

That consciously focusing on the target muscle increases its activity is well studied. In 18 resistance-trained men, EMG activity of the chest and triceps during the bench press rose when they deliberately focused on that muscle, at loads up to about 60% of their maximum; at 80% the effect disappeared (Calatayud et al., 2016). In an eight-week training study with untrained young men, elbow flexor thickness increased more under an internal than an external focus (12.4% vs. 6.9%), with no difference at the thigh (Schoenfeld et al., 2018).

Two caveats belong in honest coaching:

• More activation does not automatically mean a stronger training stimulus. The curve shows whether and how strongly a muscle is activated, not how well an exercise “works”.
• The effect depends on load. Biofeedback is strongest for technique and isolation work with moderate weights, less so for heavy sets.

This is where easyEMG comes in: your client learns muscle awareness with visible feedback, you spend less time explaining, and you get a clear picture for programming.

What easyEMG does in training

• Live curves for up to 4 muscles — wireless PicoBlue sensors (Cometa), no cables during squats, jumps or on the climbing wall
• 5 biofeedback modes — HOLD, RELAX, RAMP UP, RHYTHM, SYMMETRY; details under EMG Biofeedback Training
• Guided MVC calibration — values as % of maximum effort, stored per client and comparable between sessions
• Settings remembered per client — mode, target zone, work and rest phases are ready at the next appointment
• Training history, leaderboard per client, streaks — progress becomes visible, clients come back
• PDF report — with your logo, ideal as the outcome of a premium session
• Raw data as CSV — µV, 1000 Hz, for anyone who wants to dig deeper

On the gym floor, not in a lab

Attach the sensors, set up the tablet, go. Values are large enough to read from a few metres away, and the sensors transmit up to 10 m.

From cost to premium service

Many trainers offer EMG as a dedicated format, such as a “muscle activity check with report” or as part of a premium package. An example calculation, not a promise: with a €60 surcharge per EMG session, the 2-sensor complete package (€6,249 excl. VAT) is covered after about 105 sessions, roughly two per week over a year. What your clients pay for such a format depends on location and positioning; run the numbers with your own figures.

For studios: the licence is a site licence for an unlimited number of devices at your location. All trainers use the same app, clients are set up as client profiles.

Frequently asked questions from personal trainers

Can I use EMG biofeedback as a trainer without a healthcare qualification?

Yes. easyEMG is biofeedback and analysis software for training, not a medical device under the EU MDR, and it makes no diagnoses. Promote your service accordingly as a training and technique service, without health or healing claims.

Do I need prior knowledge or training?

No. The app explains every mode and shows SENIAM-compliant electrode placement guidance on the 3D avatar. Most trainers feel confident after the first session. More: EMG without mandatory certification

What hardware do I need?

An Android tablet (Android 8 or later) and PicoBlue sensors from Cometa, 2 or 4 channels. You get the sensors directly from us. The app is designed for Android tablets; iPads are not supported.

Does easyEMG work without internet in the studio?

Yes. Measuring and training run offline. The app only needs to go online briefly at least every 60 days to verify the licence.

What does my client take home after a session?

A report with your logo: activation per muscle, side-to-side comparison, progress compared with earlier measurements. Print it or share it as a PDF. The data stays locally on your tablet.
